Washington (CNN) – The National Republican Senatorial Committee raised $4.4 million in the month of April, and has $17 million cash-on-hand, the committee said Thursday.

"As we move closer to Election Day, it's increasingly clear that President Obama's big government, big spending agenda is putting more and more Democrat Senate seats in play. This makes it even more important to ensure that all of our candidates have the resources to run and win in November," said NRSC Executive Director Rob Jesmer in a statement.

The committee also reported that it has no debt. The NRSC reported raising $5.14 million in March.
